Around 300-400MB/s if I recall...

No.

This may provoke a strong reaction ;) but in 8 years of running a
hosting company I've never seen a NIC break in a running server. We use
multiple adapters to give fault tolerance over the switches they are
connected to , not themselves.
In any event, I'm no expert on channel bonding, but in a 2-server
configuration, where the Ips and MAC addresses are fixed at either end,
how can you use all 4 channels ? I was always under the impression that
the bonding used an algorithm based on src/dest IP/Mac to choose which
link to send data down, so in a point to point config it would always be
the same link.
We're using 2 nodes that have normal Gb-e to multiple switches using
LACP for resilience, but the drbd and heartbeat will be done over the
10Gb-e adapters, no switches just point to point fiber.

Bursts to over 200MB/s is well above Gig-e. Although yes, my average
transfer is not much above Gig-e.
